Hello,Sorry I am a beginner and it is not obvious with VM.So to see the layout I have to place an order testy each time it is not very practical. Especially when the invoice preview does not work in VM Control Panel - Shop - Invoice.The last update still does not solve the problem is it strange

The preview is merely an HTML preview of what to expect. Just forget about it. It's useful for other things, but not to preview the PDF invoice.

If you read GJCs comment carefully, you can just delete the old PDF in the invoice folder in the safe path. After that you can press the button in the order list on the old order again and the PDF will be generated again.So testing the new PDF takes just a few seconds. Delete the old one, press a button, get the new one.

You say : "If you read GJCs comment carefully, you can just delete the old PDF in the invoice folder in the safe path."Could you tell me where I can delete the old PDF. I'm not really familiar with VMThank you
